The apostle Peter viewed the transfiguration as a marvelous confirmation of the prophetic word, and by having been an eyewitness of Christ’s magnificence, he was able to acquaint his readers “with the power and presence of our Lord Jesus Christ.” (2Pe 1:16, 19) The apostle had experienced the fulfillment of Christ’s promise that some of his followers would “not taste death at all until first they see the kingdom of God already come in power.” (Mr 9:1)

It showed that Jesus had God’s approval, and it was a foreview of his future glory and Kingdom power. It presaged the presence of Christ, when his kingly authority would be complete.
